CASE FOR BTW-WINDING AND STIDLSETTING AUTO MOBILE CLOCKS.

Application filed September 12, 1922. Serial No. 587,662.

' To all whom it may concern:

Be it known that I, WIIsoN E. PORTER, a citizen of the United States, residing at New Haven, in'the county of New Haven I and State of Connecticut, have invented a new and useful Improvement in Cases for Stem-Winding and Stem-Setting Automobile Clocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

N Fig. 1, a view in front elevation of a stem- 'windlng and stem-setting automobile clock,

cased in accordance with my invention and shown as mounted in an instrument-plate, portions of which are broken away. i 10 Fig. 2, a view thereof in side elevation, with the instrument-plate in vertical section. 1

My invention relates to an improvement in cases for that class of stem-winding and stem-setting clocks designed to be installed in the instrument-plates of automobiles, the object being to produce a simple, strong, and

eflicient clock-case constructed with articular reference to facilitating the inltial installation of eight-day clocks of the character described, with provision for their easy regulation from the front of the clock '45 at any time-without demounting the same. With these ends in view, my invention consists in an automobile clock-case having certain details of construction and combinations of parts as will be hereinafter described and particularly pointed out in the claims.

In carrying out my invention, as herein shown, I employ an annular, removable clamping-ring 10 having a milled edge and formed upon its inner face with an externally-threaded sleeve 11 adaptin it to be screwed into internal threads 12 ormed just within the open outer end of a deep ceive the external threads of a removable dial-mat 17 which holds the glass or crystal 18 in place in the bezel 16. Under this construction, the bezel may be removed for regulating the clock without disturbing the clamping-ring, and so without demounting the clock, which is necessary when the bezel is made to serve as the clamping-ring of stem-winding and stem-setting clocks inserted through the instrument-plate from the rear thereof.

The instrument-plate 19 is formed with a circular opening 20 just large enough to receive the clock-case 13, which is inserted into it from rear to'front and firmly heldin place by the enga ment of the clampingring 10, with the orward face of the said late 19 at points around the opening 20 and y the engagement with the rear face of the said plate at points adjacent to the said hole of the forward ends of the legs of a stiff rectangular yoke 21 adapted to embrace the case 13 and formed with holes 22 to permit it to be slipped over mounting-screws 23 projecting from the closed back of the case 13, in which they are rigidly mounted. The projecting outer ends of the screws 23 receive nuts 24, by which the yoke is drawn forward and the clock correspondingly upper end of which is rigidly mounted in moved from it, after which the open forward endof the case is readily passed from rear to front, through the'opening 20 in the plate 19. The yoke 21 is now slipped over the screws 23 and the binding-nuts 24 applied to the screws. The ring 10 having been screwed home in the projecting forward end of the case, the binding-nuts are screwed upon the screws 23 until the plate 19 is pinched between the ring 10 and the ends of the legs of the yoke, whereby the clock is firmly installed in place. Now, if it is necessary to regulate the clock, this can be done very readily without demounting it, by simply removing the removable bezel 10. claim: I 1. In a stem-winding and stem-setting automobile clock, the combination with a case provided at its forward end with internal screw-threads, of a-removable clamp-' ing-ring provided with external screwthreads for engagement with the said internal screw-threads of the case, and also with internal screw-threads, and a removable bezel having external screwrthreads for en gagementwith the said internal screwthreads of the clamping-ring, whereby the bezel may be removed for regulating the clock from the front thereof without demounting the clock from the automobile.

2. In a stem-winding and stem-setting automobile clock, the combination with a case provided at its forward end with internal screw-threads, of a removable clampingring provided with external screw-threads for engagement with the said internal screw-threads of the case, and also provided with internal screw-threads, a removable bezel having external screw-threads for engagement with the said internal screwthreads of the clamping-ring, and also having internal screw-threads, and a dialmat having external screw-threads for en-, gagement withthe said internal screwthreads of the removable bezel, whereby the bezel may be removed for regulating the clock from the front thereof, without demounting the clock from the automobile.

3. Ina stem-winding and stem-setting automobile clock, the combination with a case provided at its forward end with internal screw-threads, of a removable clamping-ring having external screw-threads for engagement with the said internal screw-threads of the case and also having internal screwthreads, a removable bezel having external screw-threads for engagement with the said internal screw-threads of the clamping-ring, a plurality of screws projecting from the back of the said clock-case, and a mounting-member fastened to the said clockcase by the said screws and extending forward with respect thereto into position to co-act with the said clamping-ringin mounting the clock in the instrument-board of an automobile, whereby the clock may be permanently installed in the said instrumentboard and regulated from its front by theremoval of the said bezel from the said ring without demounting the clock from the said instrument-board.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
